Windows 10: Workaround for High CPU from Windows Wireless Lan 802.11 Extensibity Framework

Short version: try a USB-based WiFi adapter.


Long version:


I recently installed the Fall update for Win10 (intentionally waited) on my HP Envy laptop (Ryzen-based) and noticed the above-mentioned service was eating up ~20% CPU. This had not shown up in the past, and the solutions I found on this site either do not work or are a temporary fix...e.g. killing the task/process only helps during the current system lifecycle. It's probably a race condition issue and difficult to detect, otherwise why would this bug exist for a few years? (there are posts from 2016 and earlier on this issue)


I had a NetGear, USB WiFi adapter (AC1900/A7000) laying around from another project and gave it a try (disabled the internal WiFi, used the Nighthawk exclusively). No problems at all, network perf seems to be about the same.


I definitely recommend trying the usual methods first (driver updates/etc), but if that doesn't work out and this issue is driving you crazy, try an external adapter. I'm assuming that using the adapter either avoids the race condition or somehow doesn't even tap that extensibility framework blah blah at all....I honestly don't care, and YMMV based on your system config, but for me it just works

Windows Wireless Lan 802.11 Extensibity Framework, while watching videos spikes to use 100% ram and CPU

Having a problem with my Dell xps 13 9350, with the i5 skylake cpu, and 8gb of ram.

When watching videos (streaming/and or local). All of a sudden my video skips for a few seconds (freezing) I started looking at the task manage to see what was going on, and I could see that all of a sudden Windows Wireless Lan 80.11 Extensibility Framework
would go from using 0% CPU, and .6mb of ram to consuming 100% of my CPU and using 100% of the free ram, after a second or two, it would return to normal, but the problem would comeback a few minutes later.

wlanext.exe Windows Wireless LAN 802.11 Extensibility Framework on Windows 10 causes slowdowns of the system by using up to 90% of the RAM

Have you found a solution to this yet?

I'm using Dell XPS 13 with 8GB ram experiencing the same problem. Since I bought the PC with Windows 10, I've experienced this issue along with another issue that occurs at the *same time* for me - System and Compressed Memory Service High CPU Usage

I recent post from someone on that latter thread found a partial solution indicated here - What is the cause of a high CPU usage of 'system and compressed memory' in Windows 10?

that appeared to solve my issue with "System and compressed memory" service running high CPU and crazy RAM usage spikes, similar to what we're experiencing with "windows wireless lan 802.11 extensibility framework" service.

But I still can't solve this issue with the windows wireless lan framework service.... arghhh.
